To all whom it may concern:

Be-it known that I, EMIL .JAcENennc, a subject of the German Emperor,,and resident of 1 07 Himmelgeisterstrasse, Dusseldorf, Germany,manufacturer, have invented certain new and useful Improvements inMachines for Pasting Sheets on Boxes and Parcels, of which the followingis a state ment. The present invention relates to a machine for pastingsheets on boxes and parcels.

The essential feature of the new machine consists in the arrangement ofthe sheet applying attachment beside a shaft, 1n wh ch the boxes areconveyed from one. conveying means to another. By this arrangement it isrendered possible, that the sheets are pasted on the boites, while theseare being transferred from" the supplying conveyor to a secondconveyer.

The invention further relates to other new constructionalfeatures, whichare disclosed in a detailed manner in the hereinafter followingdescription and specified in the claims.

In the accompanying drawings a constructional form of the labelingmachine has been shown by way of exempliiication.

Figure 1 is a side elevation,

Fig. 2 is a plan,

Fig. 3 a vertical section on'the llne Al3 in Fig. 2;

Figs. 4 and 5 C-D in positions.

Fig. 6 is a section on the line E-F. I

Figs. 7-11 show the sheet in venous positions during the pastingprocess.

To the bedplate 1 of the machine are seare sections on the line curedfour standard bearings 2, in which" rollers 3, 4, 5 and 6 are journaled.These rollers form two superimposed labeling arrangements, as have beensubstantially de scribed in the United States Patent 860,148 dated July16, 1907, Patent No. 1,143,968 dated June 22, 1915. The drive iseifected from the shaft 7 by meansof the shafts 8 and the bevel gears 9.As all rollers are provided withintermeshing gears 10 they roll on eachother, the rollers 3, 4 conveying the glue from the glue vessel 11 tothe segments of the rollers 5 which draw the sheets from the piles 12and transfer them to the segments of the rollers 6, on which the sheetsare held by means of the grippers 14. The piles of sheets stand on Fig.2 in two' different opelative and the United States I slides 15, whichmay. be reciprocated in guides 16 on the standards 2 by means of lovers18. These levers ride with rollers 19 on cam disks 20 fitted to shaft 5.

In'the bedplate 1 a belt pulley 21 is journaled, which is intermittentlydriven by means of the ratchet gear 22 and the rod gear 23 from a cam,fitted to shaft 7. Over pulley 21 is laid a conveyor belt 24, whichfeeds the boxes or parcels 25 from any suitable point to the machine..Behind the pulley two plates 26 are fitted to vertically displaceablerods 27'which are adapted to be simultaneously raised and lowered bythelever 28 of a cam 29 fitted to shaft 7. The boxes are successivelypushed from the conveyer belt 24 onto these plates 26, which thereuponraise such box between the segment rollers 6. During this operation thesegmentsn'oll over the surfaces of the box, and paste the sheet in knownmanner to the latter (Fig. 7). Over these segment rollers rubber pads 30are secured to levers 31, which are fitted to shafts 32, to which arefitted levers 33 which are rotated by means of cams 34 fitted to theshafts of the rollers 6, so-that the rubber pads are pressed against theboxes and thereby press down the sheet which has been pasted onto thesame. Between the said rubber pads and the sheets pasted on project thinrods 35 fitted to a rail 36, in order to lift these sheets from thesegments and to prevent their curling in consequence of the glue appliedto them. When the pads press against the sheet, these thin rods or wires35 enter intorecesses 37 in the said rubber pads.

At the same level with the raised plates 26 two parallel rails 38 areprovided beside rests in guides 40, which are fitted to rods 41vertically displaceable in the bedplate of the machine. These rods 41adapted to be simultaneously raised and lowered by means of bell cranks42 and rods 43 operated by a. cum fitted to shaft 7. '1 11(3 slide 39 iscoupled by a rod 44 to the lever 45, which is rocked to and fro by meansof a rod 46 attached to it and a cam fitted to shaft 7, so that theslide is reciprocated. The movement of the slide and that of the rods 41are so timed that the slide, when in raised position, will be moved awayfrom the plates 26, then lowered and will, in such lowered posi tion,return and thereupon rise again. To the slide are fitted cars 47, which,when the such means the articles are transferred slide is raised,project upward between the [slides 50. These slides have pins 51 over,which engage the bifurcated ends of levers 53, to the shafts 54.of'whiehlevers 55 are fitted, which are rocked by means of rods 56 fromcam disks 57, so that the slides 50 are reciprocated. The slides havecross beams 58. to which arms 59 are fitted, which have.-bifurcated-heads 60 at their ends, in which arms 61 are pivotallyjournaled. The inwardly projecting ends of these arms 61 .are providedwith recesses 62, into which disks 63'project, which are fitted to theends of rods 64. These rods 64 project displaccably through the ends ofthe cross beams 58 and through slotted arms 65, fitted to the brackets48. By means of springs 66 around pins 67 and adjustably held by nuts 68the ends of the said slotted arms are pressed against the rod 64. Thetwo attachments which are opposite to each other and are fitted t0 theends of the cross beams turned toward the labeling devices are similarto each other but different from the other two attachments. To each arm61 of the two first attachments is fitted a rail 69 to which brushes 71are secured by means of straps 70. The other two attachments, on hecontrary, have the rails ()9 with straps 70 and-brushes 71 fitted onlyto the arms 61 at the side. A'xwe and below these brushes ades 73pivoting on shaft 72 are provided, which are drawn toward each otherbymeans of springs 74 and which rock simultane usly with the brushestoward the inside or outside respe, ively. At top and bottombifurcatedhe de 75 me fitted to the arms 59 in which arms 112 arejournalcd, which with their slot ed inner ends engage over the (33, andave at their outr ends rails 77, to which blades 78 are fitted.

When the articles are pushed onto the rails 38 the edges of the papersheets projecting at top and bottom abut against curved rails 79, whichfold over these edges onto the article and press them thereagainst. Atthe next advance by means of cars 47 the respective article arrives infront of the brushes 71 and the preceding article in front of thebrushes 71. and the blades 73, 78. Now the two slides 50 advancesimultaneously. The clamps (35, (36, 67 hold the r0ds64, so that thedisks 63 move toward springs 100.

the cross beam and thereby rock the brushes and blades 73, 78 toward theinside and against each other, so that they pass over the edges of thebox and fix down the sheet pasted thereon, besides folding over anystill projecting parts against the box and fixing such parts thereto.(Fig. 9). The blades 73, 78 therewith bear against the still, projectingcars 80 from above and below, so that these ears are sharply foldedover. Then the slides 50 reccde, the clamps (55-68 again holding therods (34, and in consequence thereof rocking the brushes and blades 73,78 toward the outside, so that the parts of the sheets which have beenfolded over are not torn off again. I

For the blades to glide exactly over the ears 80, it is necessary thatthe box lies quite straight. This is insured by means of two hooks 81,which are fitted to a common shaft 82, and are raised and lowered by anarm 83, which bears on a pin 84 in a vertically displaceable rod 85,which itself is raised and lowered by means of a lever 86 and a cam disk87.

()n the bedplatc l are fitted vertical columns 88, on which slides iii)are disposed, which carry rails 90, on which bifurcated heads 91 arecarried and in these arms 92 are arranged. The arms arccoupled to rails93 to which by means of straps Ell brushes 95' are secured, and theother cndsof said arms are provided with notches 96, into which engagedisks 97, which are fitted to rods 98. These rods project throughslotted arms 5)!) fitted to the columns 88, the ends of which arms arepressed against each other and against the rods )8 by means of ()n theends of rods 98 which are beside the disks 97 are secured rubber pads101. About the middle of euch column 88 is pivoted a double-armed lever102, the ends of which are coupled by rods 1023 to the slides on saidcolumns. To the lever 102 are furthermore linked rods 104, to whichbellcranks 105 are coupled, which by meansof rods lflfi are operated fromcam disks on shaft When the rods-104- are raised, the slides 8!)simultaneously move toward each other. The rods 98 are, howver, heldback by their friction, so that the brushcsflb rock against each otherand therefore pass along overthe edges of the box and fold over the cars80, fixing them down (Fig. 11). When the slides thereupon recede theclamps 9!), 100 will again hold the rods 98, so that the brushes arerocked toward outside and are lifted from the box. The furtluu" advanceof the articles by means of slide 39 then transfers the articles to aconveyor path or some other device. i

It is obvious that many modifications regarding the construction of thehereinbefore described machine may be made without, however, departingfrom the essence and spn'lt of iny invent-ion.
